Version Details and Security Vulnerabilities

@jest/source-map version 30.0.1 represents a minor update over version 30.0.0, primarily focusing on internal improvements or bug fixes. From a developer's perspective, the core functionality and API surface likely remain unchanged. Both versions heavily rely on the same core dependencies: @jridgewell/trace-mapping for source map parsing and manipulation, callsites for extracting stack trace information, and graceful-fs for robust file system operations. The devDependencies also stay consistent, with @types/graceful-fs ensuring proper type definitions for development purposes.

The repository field points to the same location within the Jest monorepo on GitHub, indicating that both versions are maintained under the same development umbrella. What sets version 30.0.1 apart are its upgraded release date, suggesting potentially recent bug fixes, and slightly different dist metadata, even though fileCount and unpackedSize are identical. This possibly reflects minor changes in packaging or build processes.

For developers already using version 30.0.0, upgrading to 30.0.1 is likely a safe and encouraged step, particularly if they've encountered any obscure issues or are seeking the most up-to-date and stable experience. For developers incorporating @jest/source-map into their projects for the first time, either version provides a solid foundation for handling source maps within the Jest ecosystem. The MIT license ensures liberal usage rights, and the active repository on GitHub signifies ongoing maintenance and community support. Always reference the Jest changelog for any version-specific details.
